1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveThis study aimed to identify physical activity trajectories through pregnancy and examine associations with postpartum weight retention.

methodsWe included pregnancies from one health care system from 2009 to 2020. Data were collected from electronic health records and physical activity from self-report before pregnancy and during each trimester. High, medium, and low physical activity groups were identified using discrete trajectory analysis. The outcome was the percentage of postpartum weight retention in the first year after pregnancy, measured as postpartum BMI as a percentage of prepregnancy BMI. All postpartum BMI measures from 21 through 365 days were analyzed using mixed effects regression models using R version 4.4.1.

resultsAmong 58,828 pregnancies, 54.7% were in Hispanic participants, 24.8% White, 10.3% Asian/Pacific Islander, 9.0% Black, and 1.3% other. Mean BMI after delivery was 105.2% ± 8.9% of prepregnancy BMI. Physical activity trajectories were high (3.4%), medium (64.9%), and low (31.6%). Compared with the low and medium physical activity trajectories, individuals in the high physical activity trajectory had greater odds of achieving prepregnancy BMI (OR: 1.314; 95% CI: 1.172-1.472 and OR: 1.285; 95% CI: 1.149-1.436, respectively).

conclusionsIndividuals with high physical activity from preconception through pregnancy have less weight retention at 360 days post partum than women with lower physical activity.
